Iv got a nice little radiola that was my grandfathers Im trying to get working, not sure of the modle I think its about a modle 67? Its a small table top am and short wave. It powers up Iv replaced the tubes but not the output tube and recaped Its now makeing some radio noise like picking up a station but very very faint, before it did nothing so I feel Im getting closer. I dont think the stations Im hearing is coming from the speaker? Seems to be comming from a tube or something? Any thoughts. Just to be clear I dont know much about this stuff.

The output transformer winding, or the speaker, may be fried (open) and you could just be hearing the audio vibrations from the output transformer. Disconnect the speaker from the transformer and ohm both; if one is open, that's the problem.

Thanks I was thinking the same, the speaker one this one only has one lead wired in do you know if thats right?

MY MISTAKE! I didn't bother to look at the set's schematic before I replied, thinking that this was a post-1930 RCA set. The Radiola 60 doesn't have an output transformer. The audio signal on the output tube's plate is coupled to an outboard high-impedance speaker via a large (0.5 uF) capacitor. The "faint sound" that you are hearing is probably coming from the output tube's plate choke, as it vibrates in accordance with the audio signal component.

So, now we are back to two possibilities: the output coupling capacitor is open (or much worse, shorted!) or the speaker is open. The correct speaker for this set (I think) is RCA 100-A. Using a low-impedance speaker will result in fast destruction of said speaker.

If the output coupling cap in the set is shorted, it will apply B+ directly to the speaker, quickly burning it out.

If you wanted to convert to a low-impedance speaker, you would need to install an output transformer to replace the speaker coupling cap. Its primary would need to be impedance-matched to the characteristics of the output tube used.

The speaker connects to the set via two wires, as shown on the schematic.

Disregard my last posting. I just realized that your set isn't a Radiola 60, it's a Radiola 6?. So, my original response was probably OK.

If the set has only one speaker wire, that means that one side of the output transformer secondary winding is grounded to the metal chassis, and one of the two voice coil terminals on the speaker is grounded to the steel speaker frame, so that when bolted to its chassis the speaker only needs one wire to complete the circuit.

: Thanks again Iv learned it is a modle 60-7 I have a parts radio and found the info on it. Ill try the speaker first maybe compair ohms readings for the transformer and speaker, thanks again will let you know.

Yup it was the speaker, works needs a little more work has a hum,some crackling static but picks up alot of stations and sounds ok.

Made a mistake on the modle, its a 61-7 thanks again
